SHOT BLASTING

Typically, shot blasting is one of the cleanest and fastest methods of mechanical abrasion. In addition to a “typical” coating job (if there truly is one), shot blasting can also be used for floors in sensitive areas that are otherwise “off limits” to other methods. Food preparation or manufacturing areas, clean rooms, working around sensitive inventory or machinery, or simply areas where chemical-free, dustless methods are required are all candidates for shot blasting.

The recycling wheel blast technology found in most shot blasters works by throwing steel shot or grit at a high velocity onto the surface being cleaned (such as the concrete floor). This is achieved through centrifugal force by a wheel with removable paddle-type blades that revolve at a high speed. Abrasive travels along the radial length of the blade and is thrown at a high velocity in a predetermined and adjustable direction.

Once the abrasive impacts the surface, it dislodges the coating and/or debris, thereby cleaning the surface. Shot blasting will only remove coatings 8 mils or less, if thicker, diamond grinding the coatings from the surface yields the best result. The abrasive and debris rebound into a reclaim chamber where it is recycled. The reusable abrasive is separated from the
dust and debris and is transported into a storage hopper for recirculation. Airflow transports the dust and debris
through a hose to a dust collector. 

DIAMOND SURFACE GRINDING

When it comes to mechanical abrasion methods for surface preparation, shot blasting often stands out as one of the most efficient and cleanest choices available. However, for scenarios that demand precision, versatility, and exceptional performance, the HTC 800 Planetary Surface Grinder emerges as an invaluable tool, offering a host of benefits.

Our grinders operate on a planetary grinding principle, which ensures a smooth and even surface finish. This is particularly advantageous in settings where cleanliness and precision are paramount, such as food preparation or manufacturing areas, clean rooms, spaces near sensitive inventory or machinery, or any location where dustless and chemical-free methods are essential.

Coupled with the ability to interchange diamond pads and specialized tooling, we’re able to handle any and every aspect a concrete floor can throw our way. From thick thin sets, glues, and other adhesive removals, to smooth mechanical profiling, we have the tooling, equipment, and experience to deliver your floor to the ideal specifications. 

While shot blasting relies on a recycling wheel blast technology that hurls steel shot or grit onto the surface at high velocity, the HTC 800 achieves its results through a different approach. Its planetary grinding system uses a series of grinding heads that rotate in tandem, delivering precise and consistent surface preparation.

Shot blasting can effectively remove coatings up to 8 mils in thickness, beyond which grinding the coatings from the surface becomes the preferred method. The HTC 800 Planetary Surface Grinder excels at handling thicker coatings, ensuring a thorough and efficient removal process.

Moreover, the HTC 800’s design provides a virtually dust-free experience and includes a dust collection system that effectively manages the generated dust and debris. This system efficiently separates reusable abrasives from waste materials and dust, ensuring that the grinding process remains clean and environmentally friendly.

JOINT & CRACK REPAIRS

All concrete substrate surfaces will require surface preparation before crack restoration, including crack, spall, and control joint. The first step in these operations is extremely critical. The best materials correctly mixed and applied are doomed to fail unless the concrete substrate is properly prepared. At a minimum, the concrete substrate must be prepared in compliance with minimum standards for the system to be placed per ACI, ASTM, ICRI, NACE, and SSPC Standards.

Deleterious surface contaminants and deteriorated concrete must be removed, repaired if necessary and the surface roughened and cleaned. 

The performance of elastomeric membranes such as internally flexible epoxy, requires a relatively uniform dry film thickness to resist drying shrinkage and thermal movement of the concrete while maintaining a seamless bridge or seal over the concrete.

Therefore it is critical that all mortar splatter, protrusions, ridges, penetrations, or sharp projections in the surface of the concrete, be ground smooth or otherwise made smooth, in addition to the normal surface preparation outlined above.

Before application of an elastomeric membrane system, control/contraction joints, construction joints, and cracks should be sealed with the selected system flexible sealant and coated with 20 mils of the selected compatible elastomeric membrane. This coating should extend a minimum of 6” on either side of the joint or crack.
