JANUARY MEETING

Foam Injection:

Sturctural Leveling and Concrete Lifting

Presented By: Gary Hanson, Leveltech

For our first meeting of the New Year, Westcon member, Gary Hanson of Leveltech will explain the structural leveling and concrete lifting processes that he has been using for the past ten-plus years. About six years ago, Mr. Hanson did a presentation for Westcon showing examples where he used this unique foam injection process. This procedure has been used for houses, warehouses, and commercial buildings, as well as roads, freeways and even airport runways.

The foam injection process Mr. Hanson uses comes originally from Finland. During World War II around 1940, Dupont came up with a foam to use on roofs. The Finns thought to put the foam under their roads to stop the frost heaving and discovered the foam also had the surprising strength to lift and level the road, as well as stopping it from heaving and cracking.

Mr. Hanson has been a building contractor since 1979. He has also worked as a grading contractor, doing underground drainage and landfill buttresses. For the last ten years his focus has been on geotechnical repairs.

This presentation was well received many years ago and has since, over the years, solicited calls and requests to Westcon about the foam injection process and Leveltech. Don't miss this opportunity to come and see an innovative process working wonders in the construction industry - especially if you missed the last presentation!

Mr. Hanson will also discuss:

v Concrete push piers

v Helical piers

v Grade beams

v Lightweight chemical grout injection

v Subsurface soil compaction and stabilization

v Hydraulic jacking
