UC3636-3 – UltraLite Concrete Equipment Pad 36″ × 36″ × 3″

UC3636-3 UltraLite Concrete Equipment Pad

UC3636-3 is a DiversiTech UltraLite lightweight concrete-composite equipment pad designed to provide a stable foundation for HVAC condensers, heat pumps, and other compatible outdoor equipment. It measures 36 inches long, 36 inches wide, and 3 inches high.

This pad combines the appearance and outdoor durability of a concrete surface with a lightweight engineered core. Its construction makes the pad easier to handle and position than a conventional solid-concrete slab while still providing a dependable equipment base.

UC3636-3 Dimensions and Load Capacity

The UC3636-3 measures 36 × 36 × 3 inches. This square format is suitable for many residential outdoor condensers and heat pumps, provided the dimensions and installed weight of the selected equipment fall within the pad’s approved limits.

The published allowable total load is approximately 528 pounds. The complete installed weight of the HVAC equipment, accessories, snow, ice, and other applicable loads must be considered before selecting the pad.

Always verify the outdoor unit’s base dimensions and mounting requirements. The equipment should fit fully on the pad with appropriate clearance around its base.

Lightweight Concrete-Composite Construction

The UltraLite pad uses a fiber-cement exterior over an engineered expanded-polystyrene core. This construction provides a solid equipment-supporting surface without the excessive weight associated with a traditional solid-concrete pad.

The lightweight design makes the UC3636-3 easier to transport across a jobsite and position at the installation location. This can reduce handling time, especially in backyards, narrow access areas, or locations where moving a heavy concrete slab would be difficult.

Durable Fiber-Cement Surface

The exterior fiber-cement coating is strengthened to provide flexibility and durability during transportation, installation, and normal outdoor use. The surface is engineered to flex slightly instead of cracking as easily as conventional rigid concrete.

The concrete-composite exterior is designed for long-term exposure to outdoor conditions. It is not affected by ultraviolet light in the same manner as some unprotected plastic surfaces and is suitable for exterior equipment installations.

Engineered EPS Core

The engineered expanded-polystyrene core helps reduce the overall weight of the pad while providing a stable bottom surface. Its construction is designed to resist warping and help distribute the supported equipment load across the prepared installation area.

The core can also help absorb and dampen some of the vibration produced during normal condenser or heat-pump operation. Proper equipment installation, leveling, fastening, refrigerant piping, and vibration-control practices are still required.

Textured Surface for Equipment Stability

The UC3636-3 features a textured top surface designed to improve stability and help reduce movement of the outdoor unit. The texture also assists with surface-water drainage around the equipment base.

The condenser or heat pump must still be secured when required by the manufacturer, applicable building codes, wind-load requirements, or local installation conditions. The textured surface should not be treated as a replacement for required equipment fasteners or tie-down systems.

Weather and Freeze-Thaw Resistance

The UltraLite construction is designed for outdoor use and exposure to changing weather conditions. Its vapor-permeable characteristics allow moisture vapor to move through the pad, helping reduce the expansion-related cracking that can occur in traditional concrete during freeze-and-thaw cycles.

Proper site preparation and drainage remain essential. The pad should not be installed in an area where standing water, erosion, unstable soil, or roof runoff can undermine the equipment foundation.

Suitable for Condensers and Heat Pumps

The UC3636-3 can provide a foundation for compatible residential air-conditioning condensers, heat-pump condensers, and other approved outdoor equipment. Its 36-inch square surface accommodates many common outdoor-unit footprints.

Compatibility should be determined using the equipment’s exact cabinet dimensions, operating weight, clearance requirements, and installation instructions. HVAC capacity or tonnage alone cannot determine the correct pad size.

Installation and Site Preparation

The installation area should be firm, level, stable, and prepared to resist settling. Loose soil, vegetation, roots, and debris should be removed before positioning the pad. A suitable compacted base may be necessary depending on the soil and local requirements.

The UC3636-3 should sit level and remain fully supported across its underside. An uneven or poorly prepared surface can cause the pad to shift, settle, or affect the position of the connected HVAC equipment.

The outdoor unit must maintain all manufacturer-required service, airflow, structure, and property-line clearances. Refrigerant lines, drain connections, and electrical wiring should not place stress on the equipment after it is positioned.
