Commercial Scope
Concrete Floor & Industrial Joints We Seal
Concrete floor slabs in warehouses, distribution centres, retail stores, car parks, stadiums and industrial units expand, contract and take heavy wheeled traffic. If saw-cut joints and perimeter expansion joints are left unsealed or filled with failed sealant, slab arrises spall under forklift and pallet-truck wheels and water or contaminants penetrate the slab. Our CSCS, CITB SSSTS, IPAF and PASMA certified team installs traffic-grade polyurethane, hybrid and polysulphide floor joint sealants with closed-cell backing rod and primer across the North West and UK-wide.

When to Call Us
Why Concrete Floor Joints Need Proper Sealing
Spalling and crumbling concrete slab edges under forklift traffic
01Unsealed or shrunken floor joints leave concrete arrises unsupported. Traffic-grade floor sealant supports the joint edges and prevents costly slab repairs.
Split or sunken sealant in existing warehouse and retail floors
02As concrete slabs cure and shrink, old floor sealant can split or pull away. We cut out failed material, clean and prime the joint faces, fit backer rod and tool new traffic-grade sealant.
Dust, water and debris collecting in open floor joints
03Open saw-cut joints trap dirt and allow washdown water to reach the sub-base. Flush-tooled floor sealant creates a hygienic, easily cleaned surface.
Tight handover deadlines on new-build commercial slabs
04We mobilise multi-applicator teams from our North West base on the M62/M6 corridor to complete high-linear-metre floor slab packages on programme.
Our Process
Our Floor Joint Sealing Process
Review drawings, linear metres or site photos
Send floor plans, joint schedules or photos of the slab joints so we can confirm the linear-metre rate, product specification and programme.
Rake out, clean and prepare the floor joints
For remedial work we strip out failed sealant. All joints are mechanically brushed/vacuumed clean of dust, laitance and debris.
Install backing rod and prime joint faces
Closed-cell polyethylene backing rod is set to the correct width-to-depth ratio and concrete joint faces are primed in line with the manufacturer datasheet.
Apply and flush-tool traffic-grade floor sealant
Heavy-duty polyurethane or hybrid floor sealant is gunned and flush-tooled to protect slab edges, with RAMS and QA sign-off records provided.
