Is Moisture Causing Problems?

Electro Osmotic Pulse (EOP)

STRUCTURAL TECHNOLOGIES' proprietary technology that can control movement of moisture through concrete under the influence of a pulsating electric field.

Engineered Solutions for Moisture Control

Moisture control problems are one of the most significant causes of damage to infrastructure. Major water damage caused by significant leakage is a common driver that typically motivates owners to seel out the root cause of moisture control problems. At the same time, minor moisture intrusion problems that may be less obvious can be just as serious. These minor but consistent moisture problems can lead to corrosion and structural damage or create mold and mildew problems that create unhealthy environments and costly remediation.

Moisture problems can occur in all areas of a structure – below grade or through wall and roof systems. Not limited to buildings, moisture problems extend to civil infrastructure and in industrial and energy facilities. Regardless of whether it’s a below grade leak in a civil structure, or water intrusion through a wall or building envelope system, STRUCTURAL TECHNOLOGIES can help.

 

Our holistic approach to solving moisture problems includes:
  • Technical understanding of the many varied causes of moisture problems
  • Field based investigative skills
  • Broad knowledge of the available products and where they can be applied
  • Use of Structural Technologies products for special applications
  • Field applications knowledge of the means and methods to properly implement project specific solutions

Solution-Building Areas of Concentration

Coatings Membranes

CoatingsSTRUCTURAL TECHNOLOGIES Solution Builders assist in the selection, design and detailing of various types of coatings and pre-formed membranes. While similar, coatings and pre-formed membranes may differ in overall use and performance

  • Coatings Coatings can be rigid or elastomeric and generally involve the application of material layer(s) to produce a film covering a surface. They can be designed to control water absorption, vapor transmission, and diffusion of aggressive liquids and gasses through the surface of a structure or member. Coatings can be filled with hardened aggregates and minerals to enhance wear and abrasion resistance. We assist in the selection, design and detailing of various types of coatings.
  • Pre-formed Membranes are sheet systems that may be bonded or loose-laid over the substrate. These membranes can be formulated to resist a vast variety of chemical exposures. Sheet systems require heat, tape, adhesives, or solvents to adhere overlapped seams. Sheet systems are factory controlled for thickness, dimensional stability, and internally reinforced for strength. Sheet membranes can have fabrics bonded to either or both sides to enhance mechanical penetration, adhesion, and assist in adhesion.. Typical pre-formed membranes include:
    • Thermosetting polymer sheets
    • Vulcanized rubber sheets
    • Composite systems
 

Grouting / Injection

Chemical injection

Structural Technologies Solution Builders assist engineers, owners, and property management agents in product selection, design, detailing and “means and methods” specifications of a wide variety of grouting and crack injection solutions for a wide range of applications.

Chemical grouts are injected under pressure into or around structural elements for either or both moisture control and strengthening. Moisture control pressure grouting is injected into concrete defects within structural elements to make them monolithic. Monolithic concrete is considered water-tight.

Selection of chemical grout(s) is based on many structural, environmental, and chemical compatibility issues. The material properties of the grouts must be matched with the physical nature of concrete defects. Successful grouting practice involves a blend of “art” and ‘science”.

Commonly used and specified grouts include the following:

  • Epoxy (low viscosity)
  • Structural Urethane(s) (One part, two part, various viscosities)
  • Hydrophobic urethanes
  • Hydrophilic urethanes (foams and gels)
  • Polyacrylate (High solids to low solids)
  • Bentonite (Water or plasticizer, activated)
  • Polymeric Gel (High viscosity)
  • Acrylamides (Powder or liquid pre-polymers)
  • Sodium silicates
  • Micro-fine cements
 

Joint Seals

Joint Seals

Structural Technologies Solution Builders assist in the design and detailing of various types of joint seals .Joint seals are used in a variety of applications across industries and infrastructure types, creating moisture proof seals between the connections of various types of building materials. Joint seals typically deal with either pressure and or movement in performing their function of maintaining a watertight connection at a construction joints where different material come together (or where the design has incorporated the need to compensate for movement within the structure ) .

Joint seals consist of elastomeric glands, initially applied as sealants, preformed polymers, sheet membranes and expanded gaskets. Typical examples include:

  • Pressure-rated waterstop joints
  • Water control sealants- rout & seal
  • Load supporting glands, and
  • Traffic bearing expansion joints
