Reconstituted Stone Repairs
Jan 14 2019A concrete disabled access ramp must be surfaced appropriately for safety and practicality. This London school found that their ramp was unsuitable, so they contacted us at Concrete Renovations Ltd.
The Situation
The client’s concrete ramp was designed to enable disabled accessibility but at the time, it was far from suitably equipped. The exposed and unfinished surface of the concrete ramp meant that travelling up and down it on wheels would not only be difficult, but uncomfortable too. Furthermore, the concrete ramp had never been covered with a non-slip material, making it even more challenging to climb and potentially unsafe, too.
Concrete Renovations Ltd were tasked with rectifying the issues, ensuring quality, durability and safety for all the future users of the ramp. Especially as the primary purpose of the ramp was to benefit those with disabilities.
The Execution
Our initial analysis highlighted that the concrete ramp resurfacing procedure would have to involve scrabbling the top layer of the concrete. This was necessary to remove any surface contamination and maintain a consistent level before we began to lay down our resurfacing product. We opted to remove 6mm from the top of the concrete, as this would allow us to match the original height of the ramp after our work was completed.
After the scrabbling was concluded, we opted to cover the ramp using Sikatop 77 due to its durability, high performance and heavy-duty nature; all properties which are essential for a school concrete ramp that will see regular use. To ensure the new surface was non-slip and practical, we drew a soft brush across the uncured material.
Project Showcase
School Chapel, Rutland
This school chapel in Rutland area exhibited the classic signs of corrosion to the mild steel reinforcement causing parts of the stone section to break off.
BEFORE
Reconstituted stone is a very command and widely used alternative to natural stone. To the untrained eye reconstituted stone looks very similar to the real thing, but in fact, contains mild steel reinforcement and is made in a similar manner to pre-cast concrete.
AFTER
Concrete Renovations Ltd treated the steel reinforcement with a rust inhibitor and carried out repairs to various stone sections on the exterior of the chapel using our colour matched, cementitious restoration mortar to provide a long lasting repair which is sympathetic to the adjacent stone.
The Result
A safer and more durable solution to the school’s disability access needs.
