Sealing Joints in the Building Envelope--Principles, Products & Practice (1 LU/HSW)

AIA Course: BENVO1
Learning Units: 1
Course Designation: LU/HSW

“Although they are a minor component of the building envelope, joints with sealants are often responsible for defects and failures — sometimes after only a couple of years.

These problems arise because there is often confusion as to who is responsible for design of joints and choice of sealants and because DETAILED DESIGN IS LEFT TOO LATE — so that decisions already taken make it difficult to design a satisfactory joint”

 —From Civil Engineer International:, July 1995, Report from CIRIA (Construction Industry Research and Information Association).

Waterproofing related issues constitute the lions share of post-tenancy complaints and revenue disruption and are routinely the basis of construction-related lawsuits.

EMSEAL operates at the center of a communication disconnect that often exists between the design architect responsible for selecting joint sealants and the engineers calculating joint movement.  When this conversation ignores the movement capability of the product that is expected to seal the joints, failures often result.  EMSEAL’s “Sealing Joints in the Building Envelope” seminar provides practical steps to avoid this and other common mistakes that effect joint sealing. Schedule an EMSEAL lunch seminar now or read more about it at www.emseal.com.

“We have come to realize that our projects show more problems with expansion joints than all other product categories combined. Yet, expansion joints are a miniscule part of projects in terms of construction costs. How can we work together to produce trouble-free joint seals?”

Received in a letter to our firm in 1990, this quote has been the basis of EMSEAL’s mission for 20+ years. Less than 1/2 of one percent of the budget of a structure is typically spent on expansion joints. In fact less than one percent is usually spent on all waterproofing. Yet, waterproofing related issues constitute a lions share of post-tenancy complaints and revenue disruption and are involved in an estimated 90% of construction-related lawsuits.

We can “work together” to produce trouble-free joint seals. It involves a collaborative process, begun early in design stage and includes the incorporation of a couple of simple sheets to your bid documents. Architects, engineers, and general and sub contractors everywhere are adopting our “Think, Design, Detail, Erect, Manufacture and Install
3-Dimensional Expansion Joint Solutions” approach to joint sealing. To find out how, schedule an EMSEAL lunch seminar now or read more about it at emseal.com.
