Concrete Cracking > Crack & Seat > Bristol Estate Roads


Client: Bristol County Council
Completion Date: January 2013
Contract: Crack & Seat


Webfell Minerals were awarded the Crack & Seat works on the Bristol estate roads, where resurfacing works had to be carried out over a number of visits.

Two estate roads underwent the Crack & Seat process totalling 10,000mē. This is a technique were an existing concrete slab is cracked at controlled centres to create discrete mini-slabs. These slabs are then rolled with a 20 tonne pneumatic tyred roller to seat them into the existing granular base. This creates a sound foundation for a flexible overlay, preventing reflective cracking of the new surface.

This process at Bristol was carried out by the baby of the breaker family called the Whiphammer which, because of its size and manoeuvrability, was perfect for this type of work.
