Concrete Laser Screed Technology

Colshaw Construction Group currently own a fleet of Ligchine and Somero Laser Screeds. These machines are amongst the most technology advanced machines within the industry, helping to produce the high quality floor slabs that Colshaw Construction Group are renowned for.

From Hand Lay to Laser Guided Machines, we can install high-tolerance concrete floor slabs of up to 3000m2 in a single day. The tolerances achieved with this machine in free movement slabs are FM1, FM2 (special), FM2, and FM3, and all our works conform to Industry Standard TR 34 Edition 3

Whether you are building a new refrigeration unit or distribution centre with double layer mesh and fibres, from 50 m2 to 50,000 m2, we have the solution for your needs.

Our specialist concrete laying teams are high skilled and proficient with the latest in concrete laying technologies. Regardless of which finish you require, be it a freezer floor or highly polished, our finishing teams are the best, with their attention to detail making us the forerunners in the Industry.

External Yards

Colshaw Construction Group can lay large areas of external concrete paving utilising the very latest in laser screed technology. Each project is carefully specified, calculated and indemnified by our in house engineering department to meet customer and industry specifications.

Concrete is the ideal material for the construction of parking and working areas around buildings. It provides a hard-wearing surface which drains well at low gradients. Concrete resists spillages of diesel and other petroleum-based products. Concrete is relatively light in colour and hence concrete parking areas are easy to illuminate.

Our concrete is independently CBR tested to ensure the highest quality is installed and giving peace of mind by ensuring full product trace-ability.

Colshaw Construction Group can also supply and install any surface water drainage system to large external areas such as channel drainage, slot drainage and networks of gullies to hard standing areas, to ensure the longevity and high performance of the slab that Colshaw Construction Group are renowned for, delivering your project on time, every time.

Power Float Concrete

Power float concrete results in a hard-wearing finished surface, suitable for high trafficked areas both foot and fork lift dependent on depth. Power float machines are fitted with circular pans to help smooth the concrete before metal blades are rotated over the surface adjusting the tilt to achieve a hardened surface.

Before the concrete can be power floated it has to be left to harden, so a concrete installed in the morning cannot usually be power floated until late afternoon dependent on the mix and outside conditions. Power floating produces a flat, smooth, dense finish. Min depths are 75mm bonded, 100mm un-bonded for foot traffic and designed between 150mm – 350mm dependant on loadings for trafficked areas. Drying times for foot traffic are 24 hours – the concrete dries at approximately 1mm per day, and should not be force-dried. These types of floors can be reinforced with Mesh, plastic or steel fibres, dependant on use and loadings.

Power floated floors are hard wearing and require no further finishes, however, resins, polishing and screeds can all be applied to the surface.

Why Order Power Floated Concrete with us?

We consider the finished use of the floor and can design the structural floors to meet your requirements. Our experienced team has over 35 years of input into designing flooring solutions for high street retailers, schools, offices and warehouse facilities.

Brush Finish Concrete Floors

Brush Finish Concrete Floors are typically used as a wearing surface on external yards, producing high slip resistance and allowing the water to drain to the falls created. Brushed finishes are suitable for areas trafficked either by vehicular or foot traffic and are also suitable for many types of mechanical handling plant. This type of finish is usually seen to service yards or large industrial parks, and is usually installed with a trowelled margin to the perimeter of the slab.

Brush Finished Concrete Floor Installation Process

A brushed finish is obtained by pulling a brush over the surface of the fresh concrete, after the surface has been levelled and allowed to harden slightly. The type of finish obtained will depend upon the coarseness of the brush bristles and the length and shape of the tufts. Brushed finishes are suitable for areas trafficked either by vehicular or foot traffic and are also suitable for many types of mechanical handling plant.

Brush Finish Concrete Floor Depths

Minimum depths are dependent on the weights and loadings being applied to the surface, however due to freeze thaw on external applications, the depth is typically 200mm. Drying times are 24 hours for foot traffic and 96 hours for light traffic dependent on mix designs used. We only recommend mesh or bar reinforcement in these applications due to the risk of fibres at the surface oxidizing and blowing the surface.

Top Flow Concrete

Top Flow Dappled concrete can be laid in large areas quickly. The concrete used is very fluid so the surface finish is flatter then most concrete installations.

Installation Process

A fluid concrete is installed using laser levels or guide rails to achieve the correct level, then a metal bar is lowered and raised through the concrete at right angles to drive out the air leaving a smooth surface. The minimum depth for a dappled concrete is 75mm bonded and 100mm un-bonded, this must be reinforced with a steel mesh or fibres dependent on the application.
Drying times are 1 day per mm as a guide. The surface is suitable for tiles, raised access floors and polished concrete without requiring further applications.

Typical applications offices, schools, shops, housing floor slabs.

Hand Trowelled - Easy Float Finish

Easy-float concrete results in a hard-wearing finished surface, suitable for computer floors, carpet floors or tiled areas. Concrete is laid and levelled either via pump or discharged of the back of the wagon, and when the concrete has been levelled by tamp, the concrete is hand floated with an easy-float to give a smooth finish. Whilst this finish is not as smooth as power floated, its is still suitable for carpet, screed or tiles.

Min depths are 75mm bonded, 100mm un-bonded for foot traffic and designed between 150mm – 350mm dependant on loadings for trafficked areas. Drying times for foot traffic are 24 hours, the concrete dries at approximately 1mm per day and should not be force dried. These types of floors can be reinforced with Mesh, plastic or steel fibres, dependant on use and loadings.

Tamped-texture Concrete Finish

Tamped and Textured Concrete finishes are a non-slip course finish, suitable for maximum grip for traffic. This is a cost-effective concrete laying solution generally used in steep, hard-to-traffic areas and agricultural applications.

Installation Process

A tamped finish is produced by raising and lowering a beam to compact the surface of the concrete creating a rough surface. Also various rollers and trowels can be used to give a wide range of textured finishes. Colshaw Construction Group widely tests new application and finishing methods to offer a proved and tested methods for our clients.
