HOW IS CONCRETE INSTALLED?
Once we have your instructions, we will order your chosen concrete mix from the supplier to arrive on the day of the pour.
First we grade the ground to the correct level, and place formwork where the edges of the concrete will be. Then reinforcing mesh is cut to size and put in place.
Once all final checks are done, the concrete truck arrives, and our skilled team will place the concrete and apply the appropriate finish as the concrete dries. If it's a hot day we will need to work fast, on a cold day we might be waiting a while for it to dry.
If your concrete is being sealed also, this must be done a few days later, and in good weather.
HOW DO YOU STOP CONCRETE CRACKING?
All concrete eventually cracks - this is its nature.
Concrete contracts and expands slightly as it warms and cools with the climate. The ground underneath the concrete may also shift slightly - or a lot - causing the concrete to shift also. With proper care and preparation, cracking can be largely minimized.
Steps that minimize cracking are:
Compacting the ground under the concrete
Keeping the concrete cool while curing
Cutting control joints
Placing steel reinforcing mesh in the concrete .
Placing expansion foam against walls to allow for movement.
Thicker concrete will help strengthen the concrete a little, but correct preparation and reinforcement is far more effective.
SHOULD I SEAL MY CONCRETE?
It's recommended but you don't have to.
Liquid Limestone in particular stains fairly easily. Sealing will help keep your concrete clean, and an acrylic sealer adds that 'wet look' to bring out the colour in your concrete.
WHEN CAN I WALK ON MY NEW CONCRETE?
Normally you can walk on new concrete the next day, and drive on it in 5-7 days. Always double check with your installer.
IS THIS YOUR BEST PRICE?
We will always give our most competitive price right from the start. To reduce the price further, you can choose not to have sealer or mesh, or reduce the concrete area.
HOW IS EXPOSED AGGREGATE DONE?
The aggregate refers to the stones in the concrete mix. In normal concrete bluemetal is used, as it is strong and cheap.
For decorative purposes, a more attractive stone (or mix of stones) is used, such as quartz, basalt, or even pea gravel.
The wet concrete is then trowelled smooth, left for 2 - 24 hours, and then a high pressure water spray is used to remove the top layer of cement, exposing the stones. Most installers spray a chemical on the freshly trowelled surface to aid this process, but it can be done without it.
IS EXPOSED AGGREGATE TOO ROUGH TO WALK ON?
There is a degree of skill involved involved in how rough exposed aggregate comes out. Poor workmanship can mean the aggregate is over-exposed, making it sharp and uncomfortable to walk on.
Our skilled team will ensure a top quality finish which is comfortable to walk on.
However for high traffic areas such as your back patio, we recommend choosing Honed Concrete instead
