7. Specialist Drainage Services Our trained operatives have many years of experience of rehabilitating sewerage networks utilising non-dig methods, in that way eliminating the disruption that would result from digging up busy highways. We effectively install a new pipe within the existing damaged pipe without excavation, with minimum disruption and no annular gap or loss in pipe capacity Survey will identify and locate exact positions of all defects such as cracks, broken pipes, fractures, total & partial collapses, blockages and root infestations. CCTV camera to be used is the latest fully rotating digital camera with steerable tractors and a range of up to 500m on an individual setup.

8. Waterproofing & Water Damage Treatment • We provide waterproofing services and repairs to existing water damage.We have had many years waterproofing experience and provide solutions to a wide variety of water damage problems in many different environmental conditions. • Unlike the majority of firms that provide waterproofing services, we are not affiliated to any supplier or manufacturer and select the waterproofing chemicals that we believe would provide the best solution to a specific job. • The choice of water proofing chemical used is critical, e.g. some chemicals will not work if applied to wet surfaces or substrates with a high moisture content, or a substrate with cracks.

9. Types of Waterproofing There are 2 main types of waterproofing treatment, there are treatments that penetrate the substrate providing waterproofing. For example , zycosil, a nanotechnology treatment process that penetrates the substrate and seals it or Brushbond, a crystalline water proofing technology. The crystals grow within the pores of the masonry blocking the gaps through which water can pass, effectively waterproofing the walls. The other types of treatments are the barrier type treatments in which membranes of physical barriers are placed over the substrate to stop the entry or egress of water.

10. Waterproofing Services • Our services include the waterproofing of underground structures such as water / sewage tanks, swimming pools, basement areas, foundations, concrete roofs. • We also provide remedial treatment where water damage has occurred. The full process includes identifying the source of the water, surface preparation and then application of the appropriate chemical treatment.
