Frazer stock an extensive range of clay drainage systems supplying a wide range of clay drainage products to meet the needs of specifiers, builders, contractors and ground workers involved in a variety of different projects. Products conform to EN 295: Part 1:1991 or BS 65:1991 and are manufactured under a quality management system which is approved to BS EN ISO 9001:2000.

Frazer stock clay drainage systems that are manufactured to provide high crushing and beam strengths enabling them to be laid in shallower or deeper trenches than other drainage materials. Installed cost savings can be made with clay by using less bedding material or lower cost options such as recycled or secondary aggregates. Flexible pipes require a full granular surround in primary aggregate which is becoming increasingly scarce and expensive.
