Sole tile gutters, side-pieces, round segments and other shape pieces minimise the abrasive effects of the wastewater flow, transport 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 masonry and behind the walling back side, which occur on use of common brick masonry of the gutters.
Melt basalt, contrary to commonly used competing materials, features significantly higher abrasion resistance.
For gluing of the basalt shape pieces into the sewerage gutters we recommend use of special mortar EUFIX S especially developed to this purpose.
