Plastic under the paving
I was called by one of our building contractors to analyze why a client of his had a problem with their paving. The client is a major law firm in Johannesburg and their paving was only 5 years old but was shifting badly and opening gaps in the paving. Some of the gaps were as wide as 4cm. I personally could not believe that the paving was only 5 years old and even though it was cement bevel bond and not clay, there was just no way that the paving should have deteriorated to this extent.
re lifting the driveway to remove the plastic sheeting
We lifted a section of the paving to get an idea of how the paving was stabilised and found that the paving had been laid on a waterproof plastic sheeting. I knew just then that it could not have been a master builders paving company that laid the paving and actually told him. The client told me that it was the builder that built the building that also did the paving but wanted to know how I knew. The answer was simple, how is paving going to stabilise if laid on a sheet of plastic and where is the rain water going to drain to?
Water laying on the plastic sheet
Most builders do not know the science of paving but will undertake the job for the extra cash and most clients are just too lazy and too complacent to call in someone else to do the paving. The problem is that 3-5 years down the line the paving needs to be uplifted and re-laid which just adds to the expense of the paving.
Plastic sheeting under your paving offers no stability to your paving.
If you are about to do paving, ask the company that you are considering to use, to please lay a plastic sheeting under your paving, if they agree, fire them and get a paving company that not only refuses to lay plastic under the paving but also explains why it is wrong.
Paving is a science and it should not be treated lightly or it will cost you a lot of money in the long run. Contact Richard on 084 300 4220 for more advice or a free quote on your paving.
Paving for a Posche
Most sports cars are very low and often the driveway needs to be leveled with filling and compaction to accommodate the sports car. We have just had this problem with a client in Rivonia where the underside of his Porsche and his wife’s BWM was catching the cement edging of the street and so consequently they had to leave their cars outside at night.

The existing driveway had an acute downward angle to the garages which had to be adjusted as well as the entrance from the street. Using 15m3 of filling and uplifting the entire driveway Aztec paving proceeded to recreate the entire driveway. To enhance the entrance we also built a retaining wall against the boundary wall to create a flower box all down the driveway.

Once the old paving was out, we at Aztec paving pulled fish lines at the angle that was best suited to accommodate the lowness of the 2 sports cars. Then on a gradual basis we started to add the filling and using a Bomag compactor we proceeded to rebuild the driveway slope towards the garages. The total area measured 165m2 which should indicate why we needed so much filling.

We then cleaned the old bricks, which were re-used. We only needed 400 new bricks to replace the edgebeam and replace the bricks that got broken during the uplifting. (Not bad considering that the driveway consists of more than 7000 bricks.) Once the slope and entrance were compacted with the correct angles we proceeded to repack the old bricks to maintain the previous look that the driveway had. The cost was in the region of only half what it would have cost using new bricks. The client did not bother calling for other quotes as he had previously seen the quality of the work we put out at Aztec paving, plus, he also knew that we do not over charge our clients and those are the main reasons for the referrals we get on a weekly basis.

Often a driveway just needs a spring cleaning to shine once again and the re-use of old bricks can often not only be cheaper but also maintain the original appearance that was created when the house was built.
