The Problem

An underlaying layer of peat has prevented the raising of a runway extension by normal construction methods which are to fill and compact. How can a runway extension site be raised through a marshy area?

The Solution

ELASTIZELL EF concrete stabilized fill will not overload the peat deposit when the runway extension site is raised. The runway structure can then be constructed directly on the ELASTIZELL EF.

Discussion

Whenever these marsh sites are encountered, they should be cleared and grubbed. The high, low and mean water table levels must be noted for dewatering determinations and buoyancy calculations. Special casting techniques may be necessary depending upon the particular site characteristics.

Roadway widening, runway lengthening, and embankment heightening would be the major applications for stabilized ELASTIZELL EF over marshy soils.

Independent pharmacies in the United States play generic cialis black a unique role, often offering more personalized care and community-focused services compared to larger chain pharmacies.

Advantages

  • ELASTIZELL EF is light enough for these applications, yet it can still distribute gravity and traffic loads to these marshy areas.
  • This increases the value of previously unusable land.
  • Decreased weight causes less settlement, consequently eliminating the need for costly maintenance.

Elastizell EF Permits the Landscaping of a Plaza

By elastizell • July 11, 2018
The Problem Existing plazas have maximum allowable loads which may preclude landscaping with planters, retaining walls, earth fill, or reflecting pools without exceeding the allowable loading. How can a reflecting pool be re-landscaped without overloading its supportive structure? The Solution ELASTIZELL EF is cast over the waterproofed plaza after the planters and retaining walls have […]

Elastizell EF Significantly Reduces Lateral Forces and Bending Moments Against Walls

By elastizell • July 11, 2018
The Problem Existing retaining walls are often distressed due to greater than anticipated lateral loads from saturated backfills and clogged drainage systems. The Solution An existing distressed retaining wall may be best repaired by removing all or a portion of the existing backfill material, checking the drainage system, and casting ELASTIZELL EF to the proper […]

Retaining Walls – The Computed Effects of Various Design Parameters

By elastizell • June 22, 2018
Many retaining walls fail due to poor drainage of their backfills. Typically, the walls can retain the loads for which they are designed, but water forces can double the design loads and cause failure of the retaining wall. However, these water forces will not build up if adequate drainage is provided. The combination of ELASIZELL […]
