Economy of SANIPOR®

Besides all well known advantages of so called No-Dig Technologies, Flood Grouting has exceptional characteristics.  

It uses gravity and rheology to flood, seal and rehabilitate gravity fed sewer collection systems “automatically”- segment by segment.

The collective treatment of all parts saves labor- and machine-time and money. More can be sealed for less costs.

SANIPOR® can be carried out by regional contracting companies or Public Works employees. No special equipment required.

Cost Comparison

How to cut down environmental and financial costs?

Savings with SANIPOR® results from its unique abilities

  • One segment per day saves 4 other labor days of using different methods in succession.    
  • Large reductions in pumping hours and chemical demand
  • Reduction of transportation and treatment costs of excess water
  • Prolongation of the service life of the collection system and
  • Rendering treatment plant expansions unnecessary

A quick payback period following execution is due to immediate elimination of infiltration.

SANIPOR® can be regarded and scheduled as a convenient method for maintenance. (No reduction of diameter, repeatable over decades)

Cost saving

Additional profitable benefits are

  • Anti-corrosion treatment: Concrete pipes, with biological sulfuric acid corrosion will be neutralized and a protective layer of calcium silicate will seal their corroded inner surface.
  • Reduction of root ingress: S1 is an effective inhibitor of root growth
  • Stabilization of loosened bedding material, stopping sand entering sewer pipes and preventing development of sink holes
