Block Paving Cleaning – Driveway and Patio Sealing
Block Paving Cleaning and Repair Services
When considering Block Paving Cleaning it’s important not to Jet Wash the surface directly as this can disturb the sub-base underneath the blocks causing the bricks to subside. Our Rotary Surface Cleaning Machines will ensure that any Weeds, Grass and Moss, between the gaps/joints, is safely removed without damaging the structural integrity of the structure. All of our industrial, petrol and diesel, generated systems make light work of cleaning ANY Block Paved Driveway, Patio or Pathway no matter it’s size, state or condition.
Any dips or sunken areas, that Block Paving in particular can sometimes endure, can also be repaired at this stage. By removing the blocks from the affected area, we can raise the sub-base/base sand and replace the original blocks before brushing in a fresh covering of Kiln-Dried Sand to firm up and stabilise the repair. We will also source and replace any broken bricks at the customer’s request.

Re-Sanding and Sealing Block Paving – Block Paving Protection
When the area is completely dry we can begin the re-sanding process. This is essential after a deep clean as it ensures the blocks are robust so they don’t slip or slide about. Kiln-Dried Sand is carefully brushed between each gap/joint to ensure that all the bricks are secured tightly in place. In some cases it is necessary to go over the surface with a Wacker Plate (vibrational machine) to make sure that all the sand it tight to the bottom of each gap/joint.
It is then recommended that the sealant is applied as soon after the re-sanding as possible to prevent any unwanted dirt, moss, grass or weeds getting chance to settle on the surface or between the gaps. The main purposes of Block Paving Sealers are to stabilise the joint sand, enhance the colour, protect the surface from stains such as oil etc and finally, (to quote the manufactures) “Help Prevent Weed and Moss Growth”. We’ve found that Polyurethane Sealers tend to be the best in terms of longevity and these are applied by either a Pressure sprayer or long handled roller system.
Vehicles should be kept off the paving for at least 36 hours after the sealant is applied. People and pets should keep off the area until it is completely dry (4 hours approx).
