Composite Decking products by Holbrook Lumber Company

Let's face it— there is probably no other home improvement project that brings more pleasure than a great deck.


Since 1989, Advanced Environmental Recycling Technologes, Inc. (AERT) has pioneered the use of recycled polyethylene plastic in the manufacture of composite building materials. With its constantly evolving portfolio of patented and proprietary recycling technologies, AERT has been widely recognized as a leader in resource conservation innovation and received the EPA Award for Environmental Excellence for its process of converting scrap plastic to composite outdoor decking.

AERT was recently acquired by Oldcastle Architectural Inc. The acquisition of AERT enables Oldcastle Architectural to enter into the attractive and growing category of composite decking. The MoistureShield® brand will serve to complement Oldcastle Architectural's existing portfolio of outdoor living brands. Oldcastle Architectural will further enhance AERT's commitment to safety, productivity and innovation.

Oldcastle Architectural, Inc. is the leading supplier of innovative and sustainable masonry and hardscape products for North America's building and landscaping markets. Oldcastle Architectural is the innovator behind many of the industry's well-known brands including Belgard Hardscapes, Echelon masonry products, Sakrete bagged dry-mixes and Anchor Wall Systems retaining wall solutions, among others. With over 172 operating locations and 5,300 employees, Oldcastle Architectural operates across 33 states and 5 Canadian provinces.

Due to our patented and proprietary manufacturing processes our entire Moistureshield line of decking is able to be built directly on the ground, in the ground or even under water and still maintain an industry leading, best in class Lifetime Warranty.

MoistureShield® decking products make the great outdoors even greater by inspiring care-free living while making a statement.

“Choosing MoistureShield® was the best decision ever. Walking onto our porch we had a area that always stayed slippery. No matter how many times we bleached and cleaned it nothing worked until we used MoistureShield®. It's now safe to walk on when it's wet.”
