“A finished floor is only as good as the surface it is laid on”.
We regard Surface Preparation as the main element to producing a successful flooring installation.
It is therefore essential that due consideration of the preparation is based on the following information:
- The compressive strength of the existing concrete substrate.
- Moisture content or relative humidity within the concrete substrate.
- Surface contamination i.e: oil penetration, grease, swarf build up, old coatings, adhesive and thin based underlays – these all require various methods of removal to produce a sound clean surface, prior to the installation of subsequent floor coatings and toppings.
This system will propel an abrasive at a high velocity form a blast wheel onto the work surfaces. The blasting action is contained within a work chamber fitted with a unique combination of seals, which ensure efficient recovery of the abrasive via a separation section to the abrasive storage hopper.
The linked dust collector ensures a dust free operation leaving a textured concrete. The substrate is mechanically prepared and will provide a key to all screeds and toppings. Laitance can be removed to yield a tougher and highly acceptable surface. The system can also be used in combination with Hot Compressed Air Blasting so that not only a mechanical key is achieved but a chemical bond. To prepare the substrate to accept Resin Systems and Screeds.
Concrete Floor Planing
This is a system of flails loosely mounted on a rotating drum, which hammer and scratch the surface to obtain the desired effect and reduction of concrete floor levels.
You can choose amongst the flail types available, and vary their composition, such as, Tungsten Carbide Tip flails for roughening and cleaning concrete and asphalt floors, Beam flails for the removal of paint coatings, Milling flails for soft and hard grade floor materials, Star flails for the removal of rust and scale, Square flails for the removal of brittle and hardened coatings, fine and course brushes for careful treatment of surfaces are all available.
Again this system can be used in conjunction with Hot Compressed Air so that a mechanical key is achieved and all the surface contaminants are driven out.
Diamond Grinding & Surface Preparation
HTC Plantar Diamond Grinding, Vacuum assisted or wet applications. Four head machines that will remove surface coatings, surface laitance and smooth rough or uneven floors to produce a smooth surface. This machinery can also be utilised for Diamond Polishing of Concrete & Terrazzo Floors.
Removal of Oil Contamination
The system is a combination of propane gas and compressed air ignited in a chamber at a temperature of approximately 1,000 degrees centigrade, which exits the head at 1,000 feet per second.
When the heat blast comes into contact with the existing substrate it will cause any water, oil or liquid contaminants to vaporize in the top 3mm or 4mm of the concrete, and these will very quickly evaporate from the surface and be blown away by the heat leaving the surface capillary pores empty and open. Primer is applied to a hot surface and the immediate of this is to thin down the resin Epoxy allowing it to soak into the capillary pores very noticeable as the resin mes hot, has Once in, the Epoxy Primer will thicken-up and cure rapidly because of the heating, which structure occurred preventing any migration of oil or moisture from below locking the surface of the concrete.
Floor Stripping & Diamond Grind Surface Preparation
Ride on stripping for removal of Vinyl sheet and tiles, ceramic tiles, wood block, prior to surface preparation. Aids the removal of adhesive latex, underlay and planetary grinding to produce a smooth clean concrete substrate.
