History of EIFS

During the past 10 years there has been a housing boom for which we may never see again.  Part of this increased demand for housing has lead architects and builders to find new ways of cladding the exterior of homes.  Unfortunately, one of the products used was Exterior Insulation Finish Systems (EIFS).  EIFS is a non-load bearing exterior wall cladding designed to be attached to wall sheathing with an adhesive or mechanical fastener.  The system typically used in residential construction is categorized as non-drainable or barrier type system.  The system consists of four components:

1.  Panels of expanded polystyrene foam insulation glued, screwed, or nailed to the substrate.

2.  A base coat that is troweled over the foam insulation panels.

3.  A glass fiber reinforcing mesh that is laid over the polystyrene insulation panels and fully embedded in the base coat.

4.  A finish coat that is troweled over the base coat and the reinforcing mesh.

EIFS Problems

The inherent problem with the system is that once water penetrates the surface of the cladding, the system has no way of weeping or letting the water return to the exterior of the house.  Without a mechanism for allowing the water to return to the exterior of the house, the water remains in contact with the sheathing and structural members of the house and eventually will cause rotting due to excessive moisture levels.

Weeks Engineering Construction & Consulting, LLC structural engineers can provide solutions for EIFS clad houses.  These may include damage assessment reports, maintenance guidelines, and removal of EIFS.  We are fully insured with Workman's Compensation Insurance and General Liability Insurance.

EIFS Contractor

Q.  Has your contractor installed EIFS and if so, what were their technical qualifications to determine if an EIFS system would be an appropriate house covering?

A.  Weeks Engineering Construction & Consulting, LLC has never installed EIFS on any project because it was apparent many years ago that the product was defective.  It is interesting to note that contractors who installed EIFS on homes are now wanting your business to remove it.

Q.  Ask your contractor how many EIFS removal projects they have completed.

A.  Weeks Engineering Construction & Consulting, LLC has successfully removed EIFS on over 20 projects and has consulted and inspected more than 50 homes.  The staff has registered engineers and home inspectors on staff and can provide valuable structural remediation for your project.  We have more experience in EIFS removal, testing, and inspection than any Company in the Birmingham area.

Q.  If you are involved in a lawsuit related to an EIFS home, would your contractor be able to testify on your behalf for the EIFS removal process and findings as an expert witness?

A.  Weeks Engineering Construction & Consulting, LLC has extensive experience working with attorneys as an expert witness due to our qualification as engineers, our significant knowledge of the product and application, and years of experience.

Q.  Where can I find a list of similar projects you have done?

A.  You can view pictures of completed projects or contact us to talk with one of our engineers about the process involved and how we can make your project unique.

Q.  Can you give me some client and business references that I can call?

A.  Please contact us for business and client references.
