Our Work

Snowden Seamless Flooring’s work is carried out by two highly-trained, experienced, and self-contained construction teams. Each team has its own devoted Somero 240 Laser Screed for the construction of ground floor slabs. Though this is the core of the company’s business, it also undertakes large upper floor projects. Where sub-base preparation is required, each construction team has Snowden’s two D5 bulldozers at their disposal. The company also owns two Somero Topping Spreaders for projects where a coloured and/or extra abrasion-resistant finish is required. Utilizing this substantial plant investment, Snowden Seamless Flooring lays up to 600,00m2 of floors per year.

Construction Teams

Each Construction Team consists of separate Laying, Finishing, and Saw-Cutting units, all with their own foreman reporting to Snowden’s overall site-based project manager. Each team is allocated a solely-dedicated office administrator to coordinate materials deliveries, transport, and accommodation. All operatives are CSCS registered, and either possess or are working towards NVQ certification in their particular specialism. All machine operators are fully trained and certificated. Snowden Seamless Flooring has an exemplary safety record, and every employee is trained to current Health and Safety standards.

Laser Screed The introduction of the Somero Laser Screed in the 1980’s revolutionized the construction of ground floor slabs.

Formerly slabs were built using the slow and joint-intensive ‘long strip’ method. Laser Screed brought increased pour sizes, reliability of tolerance, and reduction of joints. The resulting combination of faster construction programmes and significantly reduced slab maintenance achieved considerable cost savings.

Laser Screed Construction of a Ground Floor Slab: A Brief Description

The construction process begins with the preparation of the sub base. Temporary protective sheeting is then taped to the surrounding cladding to prevent damage from concrete splashes, and expansion joint is fixed to all column bases and slab intrusions.

Next a polythene slip membrane is laid over the sub base. The membrane will be lapped a minimum of 300mm to all edges.

Normally starting in the left hand corner of the building, layers of wire mesh reinforcement are then laid lengthways (4.8 metres) the full width of the pour, and packed to the correct cover using grade-plate spacers. (Alternatively steel fibre reinforcement is added to the concrete and poured directly onto the membrane).

As the pour proceeds further sheets of mesh are laid in rows. Concrete is then dispersed over the reinforcement from the chute of the concrete wagon.

The Laser Screed’s on board computer will then be set to the required datum points. Its telescopic boom will go out over the concrete and then screed it back to the correct level. Levels are automatically re-checked and verified throughout the pour. The process will then continue from left to right until the entire surface of the floor is screeded and the Laser Screed reverses out of the entrance door.

Powerfloating operations will start as soon as the concrete has stiffened sufficiently. Panning machines are used before bladed machines work the surface to the required finish.

The slab will then be sprayed with a curing membrane which contains moisture within the slab and thereby ensures that it reaches its required strength.

Unless the slab is a jointless steel fibre reinforced design, slab construction is completed by saw cutting joints at not greater than 6m centres. This operation controls the natural post-construction shrinkage of the slab.
