Crack and Seat is a technique where an existing concrete slab is cracked at controlled centres to create discrete mini slabs. These slabs are then rolled with a 10 or 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.
Webfell Minerals have three machines capable of producing this foundation overlay.
The smallest machine, the Whiphammer, is used on estate roads and concrete car parks and materials stocking areas. Here the concrete is cracked to produce a star pattern of slabs ready for seating and overlay.
On main highways one of the two Guillotine Breakers are used. Here the slab is cracked transversely across the carriageway width at defined centres, typically 1 metre, to produce the mini slabs. Seating and overlay then takes place.
