Thermocure concrete cylinder curing boxes. Home of the original Thermocure II, the box that heats and cools
THERMOCURE II, ASTM requires the curing of test cylinders under controlled conditions during the first 48 hours in the field. Most likely, all 50 states will soon follow suit. That means maintaining the cylinders within a range of 60*– 80*F on the job site. Other curing methods aren’t reliable enough to ensure compliance. Thermocure II, however, makes it easy.
The right temperature in every environment.
In the field, so many variables can send cylinder temperature outside the required limits: not just extremes in outdoor temperature, but the heat that naturally occurs during the curing process. That’s why Thermocure maintains automatic temperature control with a heat pump that both heats and cools to within 2 degrees of the ideal temperature…well within ASTM limits.
Sheet Gaskets
Construction Innovations Sheet Gasket is used as a bond breaker and sliding surface in bridge construction. The material for the sheet gasket is treated on both sides with a parting agent to prevent adhesion to working surfaces.
Longitudinal Joint Ties

Longitudinal joints are used to relieve warping stresses and are generally needed when slab widths exceed 15 feet. Widths up to and including 15 feet have performed satisfactorily without a longitudinal joint, although there is the possibility of some longitudinal cracking. Longitudinal joints should coincide with pavement lane lines whenever possible, to improve traffic operations. The paint stripe on widened lanes should be at 12 feet and the use of a rumble strip on the widened section is recommended. Load transfer at longitudinal joints is achieved through aggregate interlock. Longitudinal joints should be tied with tiebars to prevent lane separation and/or faulting. The tiebars should be mechanically inserted and placed at mid-depth. When using Grade 40 steel, 5/8-inch by 30-inch or 1/2-inch by 24-inch tiebars should be used. When using Grade 60 steel, 5/8-inch by 40-inch or 1/2-inch by 32-inch tiebars should be used. These lengths are necessary to develop the allowable working strength of the tiebar. Tiebar spacing will vary with the thickness of the pavement and the distance from the joint to the nearest free edge. source FHWA
Custom Dowel Basket Assemblies
RSR Basket
When using dowel baskets, the dowels must be properly aligned and the dowel basket firmly anchored to the base course. The FHWA recommends that the dowel baskets be secured with steel stakes with a minimum diameter of 8 mm (0.3 inches) embedded at least 100 mm (4 inches) in stabilized bases, 150 mm (6 inches) in treated permeable bases and 250 mm (10 inches) for untreated bases or subgrade. Further, a minimum of 8 stakes per basket is recommended.
Waterstops
Waterstop plays a critical role in the integrity of concrete structures. It provides a fluid-tight diaphragm when embedded in, and running through concrete joints. Earth Shield Thermoplastic Vulcanizate Waterstop (TPE / TPER / TPV).
