How long does the process take for a typical earthquake repair?

Every job has its own quirks. Typically by the time all of the stages are complete, the works will take around two to three weeks.
With each quotation sent out, you will receive our homeowner information booklet. In this booklet it clearly outlines the whole process from start to finish.

Send us your plans and scopes

If you already have a plan or a scope of works, you can either email us or use the upload tool here (Link to upload plan tool on contact page) to save time. We can quite accurately price you project off that.

From the time I accept your quotation, how long before you can start work onsite?

Generally around 3 weeks. This can depend greatly on weather.

My neighbours concrete is bright white. Will my concrete be that bright too?

There are low cost options including adding some black oxide to the concrete the time of batching. This takes that bright glare off the concrete and tones it down to a mid grey. This is just one option.

Will the repairs be loud?

Concrete Saws, Jackhammers, Plate Compacters, Excavators, Bobcats, Hammer Drills, Concrete Trucks, Water Blasters… They are all very noisy. Please be tolerant, as they are all needed to complete the job.
Some of this equipment may cause vibrations too.

Since the earthquake, my driveway now holds water after it rains. Will I need drainage?

Yes and No. There is no doubt that since the earthquakes the levels on a lot of properties have all changed. In some instances it may be that some more plants or gardens just need to be removed to allow the water to drain away adequately. In some cases, drainage may need to be installed. We should be able to assess this at the time of the quotation.

Will my concrete crack again?
Yes. A common misconception with concrete is that your new concrete will not crack. Cracking is a very frequent cause of complaint in the concrete industry. Cracks in concrete can be the result of or a combination of a number of factors. These include, drying shrinkage (The most common), thermal contraction, subgrade settlement, applied heavy loads and Christchurch’s specialty, earthquakes!

All though we use all possible measures and best practice, cracks will occur! All steps are taken at the preparation, placing and finishing stage (excavation and base preparation) and there are a number of steps taken during and after the concrete is placed. We go into this in further detail in your homeowner booklet.

Does my concrete need to have cuts in it?

Definitely.  The cuts in the concrete helps induce a crack in the concrete along the cut.  We cover this in great depth in your homeowner booklet.

Reinforcing?
Do you add steel reinforcing to the new concrete?
Only if the client requests it. As a rule of thumb, most insurance works are like for like also. When dealing direct with the client, we will only add reinforcing if it is requested.

Should I add steel reinforcing to my new concrete?
We absolutely recommend it. Although steel mesh does not necessarily prevent cracking in concrete, it does help hold it together. Also, if cracks do develop, they will stay far finer than would otherwise if there is no steel mesh.

Should I seal my new concrete?
Why do we seal concrete? Well, it is done for a number of reasons: 

  • It seals the pores of the concrete and provides a barrier to prevent dirt, grease and mould from staining the
    concrete surface.
  • It creates a very hardwearing surface.
    Provides good UV protection for coloured concrete surfaces.
    Helps with the curing process.
  • It brings out the colours in the concrete oxides.
  • It seals off any minor cracks that may have formed preventing dirt and moisture from entering the cracks. This
    will help prevent spalling over time.
  • It gives the concrete a wet look.

The concrete sealer does unfortunately break down over time. This is due to a number of factors with traffic and the sun being the two main culprits. To prevent the surface underneath the sealer being damaged, a new coat of this sealer should be applied every one to three years depending on the amount of traffic the area receives. It is usually very noticeable when it is time to reseal the concrete, as it will start to lose its sheen. Give us a call when you feel it is time for
advice on resealing options.

Which surface finish is right for me?
There are many considerations when deciding.  Ranging from the final look, the cost through to the use of the surface. Check out the FINISHES tab on this page.
My driveway only has some cracks. Does it all need to be replaced?

Not necessarily. Depending on the final look you would like to achieve, there are many options tom consider. You may only need to replace parts of it. Then you may decide to add an overlay to give it a brand new look. Have a look at our section on overlays here (link to overlays in finishes)

I live on a property with shared units. Can you cater to all the tenants?

Yes we can. We have a great deal of experience in shared properties. We do have certain processes which we follow which help the job flow more smooth for all involved. We can explain this in more detail over the phone.

Consequential damage

Demolition and the removal of concrete require some pretty serious equipment. Our teams are very experienced and take all due care but sometimes some damage may occur which is completely unintentional. Please see the terms and conditions at the time of your quotation regarding consequential damage.

ASPHALT

concrete finishing Rangiora, driveway sealcoating Rangiora, types of concrete driveways

You see it everywhere, footpaths, roads, driveways.  It is commonly chosen for a finish for a driveway in residential settings as it is at the lower end of the price range in finishes and can be a lower maintenance option than some decorative concrete options and paving.  It is a dark colour so blends in to most settings.

Things to remember about Asphalt finishing:

  • Even though it is flexible, it is not as hard wearing a surface like concrete.  If you have a driveway shape that would depending on your vehicle screwing its tyres, the surface will wear prematurely. This is made even more apparent in the summer months where the asphalt can heat up and become far softer.  This is a common occurrence and should be considered when selecting your finish.
CONCRETE OVERLAYS

concrete finishing Rangiora, driveway sealcoating Rangiora, types of concrete driveways

A concrete overlay is a great option growing rapidly in popularity. Overlays can come I many forms but typically are a cementitious overlay used to resurface existing or new concrete.  They are a great option for an existing driveway that may have some cracking or earthquake damage but may not necessarily need the whole slab replaced.

There are many looks that can be achieved by installing these overlays from plain concrete, a tiled or paved look, add decorative borders or it can even mimic exposed aggregate.

It is also a great option for an existing property where the home may be renovated and the driveway needs a revamp too. These overlays can be used in internal applications also.

Things to remember with Coloured Concrete:

  • The concrete surface must be suitable.  Although we cannot guarantee against cracks, some cracks can be repaired and may not necessarily return, at least not to the extent where it will affect the final look of the overlay.   If the cracking is too extreme, an overlay would possibly not be suitable.
COLOURED CONCRETE

concrete finishing Rangiora, driveway sealcoating Rangiora, types of concrete driveways

Coloured mineral oxide powders can be added to the concrete at the batching plant and the entire mix of the concrete is coloured. This is a very long lasting concrete finish, which is growing rapidly in popularity because it is a very hardwearing surface that will last without being sealed.

Things to remember with Coloured Concrete finishes:

  •  It is a natural product. The concrete does look very mottled. We acid wash and seal the product, which does even the colour but the colour can change dramatically day by day. Due to concrete being very porous, it will change colour through moisture ingress from both on top and underneath the slab. For many people, this is what they find attractive about it.
  • The colour may not be exactly what you have chosen. Because the concrete is made from natural sand and stone. The concrete itself can change colour from day to day, even load to load of concrete. What you have seen in a photo or in a display should be used as a guide only. It is NOT paint. Please consider this carefully when making a decision on choosing your finish.
  • Decorative Saw cutting is a great upgrade to your coloured or plain concrete. It gives the look of large pavers without the hassle of weeds growing through and pavers moving up and down over time. Talk to your PM about your options. These are usually cut into 1m X 1m approx. squares.
CHIP OR CHIP SEAL

Although these sound very similar they are quite different.

Chip

A Chip driveway is popular on rural properties.  The existing surface is excavated and hard fill is installed and thoroughly compacted.  A chip aggregate or your choice is then spread on the surface.  Leaving the natural look of stones.

Chip Seal

This is essentially what you will see on a typical rural road or highway.  It is a similar look to a chip surface and the preparation is very much the same.  The main difference is that tar is spread over the surface prior to laying of the chip aggregate.

STAMPED CONCRETE

concrete finishing Rangiora, driveway sealcoating Rangiora, types of concrete driveways

Stamped or imprinted concrete finishes have been a popular finish since the 1970′s. With the large selection of colours and the growing catalogue of patterns and textures to choose from, there is a look to suit all projects. Stamped concrete is the process of colouring freshly laid concrete, then when the concrete is at the appropriate stage of hardening, a powder or liquid release agent, is applied to the surface of the concrete. It is then “stamped” using a textured and or patterned mold, which is chosen by you before work has begun. In the following days, once the concrete has hardened, one of our team will return and wash off excess release agent. The concrete is then sealed to protect and also enhance the appearance of the new concrete finish.

Things to remember with Stamped Concrete finishing:

  • It does cost more than other finishes due to the extra work and products involved.
  • It does require slightly more maintenance than other finishes. Because it has the release powder on the surface, this needs to be protected by the sealer to stop the colour wearing out. On driveways, this needs to repeated every 1-3 years depending on the amount of traffic it receives
PLAIN CONCRETE

A concrete overlay is a great option growing rapidly in popularity. Overlays can come I many forms but typically are a cementitious overlay used to resurface existing or new concrete.  Driveway sealcoating is a great option for an existing driveway that may have some cracking or earthquake damage but may not necessarily need the whole slab replaced.

There are many looks that can be achieved by installing these overlays from plain concrete, a tiled or paved look, add decorative borders or it can even mimic exposed aggregate.

It is also a great option for an existing property where the home may be renovated and the driveway needs a revamp too. These overlays can be used in internal applications also.

Things to remember with Plain Concrete:

  • Concrete is a natural product and cures over a period of a few months. This curing does not occur evenly. It is expected that your new concrete will have a very mottled look. Some jobs much more so than others. This is far more apparent with plain and coloured concrete.
  • When plain concrete is laid it does look very bright. Over time the surface does break down and fade to grey like the old driveways and paths you see around Christchurch. There are a number of options to upgrade and colour your concrete. We recommend adding a small shot of black colour to the concrete. This can be done at a very reasonable cost and really takes the brightness away from the new slab. This can be discussed with your PM or at the time of quoting.
EXPOSED AGGREGATE

Exposed Aggregate is concrete, which has the surface of the finished concrete “exposed” to reveal the aggregates in the concrete. It is very popular throughout New Zealand for its hardwearing surface and. It is especially suited to driveways and high traffic areas.

Things to remember with Exposed Aggregate finishes: –

  • It is a natural product; therefore you always get inconsistencies within a job. The stone density, depth of exposure and colour of stones do vary even within small concrete slabs. This is to be expected and part of the reason it is so popular.
  • It is a messy job. The surface of the concrete finish is has a surface retardant sprayed on the concrete when the concrete is still in its plastic state, which stops the surface hardening. The following day, the surface is then water blasted off to reveal the aggregate. Although all care is taken, it is still a messy job. Our team do a thorough clean up but some mess is to be expected.
STENCILLED CONCRETE

concrete finishing Rangiora, driveway sealcoating Rangiora, types of concrete driveways

A very popular look for median strips and traffic islands.

Stencilled concrete provides a very hard wearing surface that gives the look of brick or tile.

Stencilled Concrete is the process of laying a cardboard stencil pattern into freshly poured wet concrete and trowelled the stencil into the surface.

Colour Hardener is then applied (see coloured concrete) either by way of broadcasting and trowelling into the surface.  stencil is then removed to reveal the pattern of the stencil in the concrete. The concrete is sealed (see sealing) to protect and enhance the appearance of the finished concrete work.

Things to remember with Stamped Concrete finishing:

  • Installation of Stencilled Concrete is labour intensive so therefore is at the high end of the price range of finishes.
