Water Damage from Leaking Shower Stalls
January 24, 2018 1:53 pm Leave a Comment
Have you ever had to have a leaking shower pan for a tiled shower stall replaced, only to have a recurrence a few years later? If so, it is likely that it was not properly built and/or repaired. In most installations, the shower stall is constructed with an underlying one-piece flexible membrane of PVC that is attached to the wall studs before the backer board and wall tile is installed. No nails or screws should penetrate the membrane below the level of the curb of the shower stall. The only opening in the membrane below the curb must be the hole for the shower drain to connect to the house plumbing. The shower drain is designed to allow water on top of the membrane to flow into the drain via weep holes for that purpose. (more…)

The wet, relatively warm weather recently experienced in the southeast has caused a high incidence of mold and other fungal growth complaints in homes and other structures. Engineers at Warren are often called upon to investigate the cause(s) of these problems. (more…)
Workers Compensation Subrogation Potential: Top 4 Data Needs for Experts
November 24, 2014 9:53 am Leave a Comment
Oftentimes, an insurance adjuster may suspect that the potential exists for a workers compensation claim to be subrogated, but would like a second opinion from an expert before launching a full-blown investigation; alternately, the adjuster may hold the opinion that the subrogation potential is not great, but would like a second opinion for confirmation of his view.

Injury on Power Buggy
August 11, 2014 10:17 am Leave a Comment
When an operator is thrown from a ride-on vehicle when it tips over, such as a mud buggy, serious injury or death can result. In one such case we investigated, the issue centered on the maintenance of the vehicle, specifically whether a maladjusted hydrostatic drive caused the braking mechanism to malfunction. (more…)
Bolted Connection Failures
April 28, 2014 9:47 am Leave a Comment
One of the most common features of machinery, consumer products, and assemblies of any type is the bolted joint. Sometimes the joint fails, with results ranging from inconsequential to catastrophic. The design of a joint is in the purview of an engineer, who must consider the material to be joined, the geometry of the joint, the loads imposed on the joint, the strength of the connectors (i.e., bolts, screws) environmental effects (i.e., temperatures, corrosion) and perhaps other factors.

Freeze Damage to Fire Sprinkler Systems
January 10, 2014 10:57 am Leave a Comment
The ongoing frigid temperatures serve as a reminder of the many investigations by Warren engineers involving fire sprinkler systems that have failed when some part of the system was exposed to the sub-freezing conditions. Interestingly, failures do not necessarily occur within the area of greatest freeze exposure, as the failure mechanism is the extreme pressure that results from the growth of an ice plug inside the exposed pipe in which the high pressure will rupture the weakest component which may even be located in a heated area of the sprinkler system.
