1. Faded or stained surface.
Faded or stained surfaces on block paving can be caused by many factors, such as exposure to the elements, vehicles driving over the surface, and a build-up of dirt, moss, or algae. Over time, this can cause the blocks to lose their colour and shine, making the surface appear dull and uninviting.
A deep cleaning and resealing process are necessary to address a faded or stained surface. This typically involves pressure washing the surface to remove any dirt, moss, algae, and any old sealant that may have been applied in the past. After the surface is cleaned, a new sealant can be applied to protect the blocks and restore their colour and shine.
It's essential to use the appropriate sealant for the specific type of block paving you have, as some sealants are better suited for certain types of blocks and can also be used to change the colour of the surface.
2. Sinking surface.
An uneven or unstable surface on block paving can be a severe safety hazard and a sign that the sub-base or bedding material underneath the blocks has shifted or eroded. This can cause the blocks to sink or tilt, creating an uneven surface that is difficult to walk on or drive over.
The affected blocks will need to be removed and replaced to address an uneven or unstable surface, and the sub-base will need to be re-levelled and compacted. This process involves excavating the affected area, removing any loose or unstable material, and replacing it with fresh, compacted sub-base material.
Then the blocks are then put back in place, levelled, and compacted again to ensure a stable and even surface. The jointing sand between the blocks also needs to be replaced, and new paving blocks might need to be cut to fit the space properly.
Please note that if the sub-base problem is not fixed correctly or left unattended, the problem might reoccur, requiring another refurbishment in the future.
3. Cracks or missing blocks.
Cracks or missing blocks in a block paving surface can appear because of tree roots, heavy vehicle traffic, or even regular wear and tear. These issues can be unsightly and a safety hazard, as they can cause the surface to become uneven and unstable.
It is vital to determine the root cause of the problem, or the cracking might reoccur. For example, if tree roots cause cracks, then consider removing them. If the damages are caused by heavy vehicle traffic, consider re-routing the traffic or reinforcing the surface.
To resolve the issue, the affected area must be removed and replaced to address cracks or missing blocks. This process typically involves removing loose or damaged blocks and replacing them with new ones. The jointing sand between the pavers should also be removed and replaced. The new blocks require levelling and compacting to ensure a stable and even surface.
4. Excessive water ponding.
Excessive water ponding on a block paved surface can be a sign of poor drainage and can lead to various problems, such as damage to the sub-base, erosion of the surface, and even flooding.
To fix excessive water ponding, the surface needs to be graded appropriately to improve drainage. This process typically involves excavating the affected area, removing any loose or unstable material, and replacing it with fresh, compacted sub-base material. The sub-base should be graded to ensure that water flows away from the surface and into a drainage system.
It might be necessary to install a drainage system if it still needs to be implemented. Also, it's crucial to ensure that gutters and downspouts are working correctly and redirect surface water away from the area.
The surface might also need to be re-levelled after grading the sub-base to ensure stability. Ensuring that the jointing sand between the blocks is clean and at the correct depth will help to prevent water from pooling on the top.
5. Block Paving Refurbishment - Summary.
The main signs that block paving need refurbishment are usually visible so that the solutions can be implemented accordingly. Faded or stained surfaces can be restored by deep cleaning and resealing. Sinking block paving can be fixed by removing and replacing the affected blocks and re-levelling the sub-base.
Cracks or missing blocks can be repaired by removing and replacing the affected pavers, replacing the jointing sand, and fixing the root cause of the problem. Weed growth can be resolved by adding new jointing sand, and excessive water ponding can be resolved by adequately grading the surface to improve drainage and prevent water damage.
It's important to note that the frequency of block paving refurbishment depends on factors like the quality of the materials used, the level of usage, how well it's been maintained, etc.
In general, block paving should be inspected at least once a year, and any signs of wear and tear should be addressed as soon as possible to prevent further damage and prolong the life of the surface.
Hiring a professional and experienced contractor for block paving refurbishment is crucial. They can help you to know the best solution to fix the problem by evaluating the surface, determining what needs to be done, and providing a detailed estimate for the work.
