INTERLOCK MAINTAINANCE

Polymeric Sand Fill / Re-leveling

Weeds push and spread interlocks apart allowing water to enter the joints, washing underneath foundation material which leads to sinkage when walked or driven on.

The solution is to de-weed using high pressure water with corrects nozzle and hand pick roots. Sand fill polymeric sand consisting of adhesives which is later activated through a 3 stage misting process.

Polymeric Sand is a dry mixture of calibrated sand, polymers, binders and dedicated controlling agents technically designed to bind together in horizontal pavement joints. Its high polymer content and its unique composition will generate optimum results. It will resist most weather conditions such as freezing, thawing, rain and wind.

Advantages

Here we can see a weed infested driveway, causing the interlocks to spread, shift and allowing water to enter the joints

After a complete wash and clean up, we apply the proper colour polymeric sand into joints and brush over the interlocks a few times ensuring all joints are filled

Blowing the driveway enables the sand to spread evenly and clean the dust off the surface, as it can stain the interlock

The final step is a 3-stage misting procedure that locks the sand in by activating the adhesives

De-weeding is a 2-day process, depending on the size of the driveway. The final product resembles a clean driveway that is properly sealed.
