Sole tile gutters, side-pieces, round segments and other shape pieces minimise the abrasive effects of the wastewater flow, when transporting inorganic particles of various sizes, particularly at the sewerage bottom.

Simultaneously, they feature significantly lower number and length of longitudinal housing and contacting interstices as compared to the brick masonry. Therefore, there is no risk of interstice erosion, penetration of wastewater into the masonry and behind the walling back side, which occur when using common brick masonry of the gutters.

Melt basalt, contrary to the commonly used competing materials, features significantly higher abrasion resistance. We recommend the use of special mortar, named EUFIX S, which is especially developed for gluing of the basalt shape pieces into the sewerage gutters.
