Thin Spray-On Liners (TSL)

Elastic polymer-based thin spray-on liner (TSL) for surface reinforcement and weathering protection of soil, rock and coal strata

Thin spray-on liner (TSL) products offer a highly effective solution for surface stabilization, support, and protection in mining and underground construction environments. These advanced technologies are ideal for reinforcing and waterproofing exposed rock or strata, as well as mitigating the effects of weathering. Certain TSL formulations are characterized by high elasticity and elongation after curing, enabling them to accommodate minor ground movements without compromising their integrity. In addition to mechanical reinforcement, TSLs are capable of providing surface sealing to inhibit the ingress of water and the escape of gases. Their application in thin layers significantly reduces the volume of material required on-site, simplifying logistics and improving operational efficiency within the confined conditions of underground works.
