Biokil Crown 8mm Membrane – Clear
High-Capacity Cavity Drainage Membrane for Below-Ground Waterproofing
Biokil Crown 8mm Membrane – Clear is a robust, high-capacity cavity drainage membrane designed for internal waterproofing applications in basements, retaining walls, and other below-ground structures. Manufactured from clear high-density polyethylene (HDPE), the membrane features 8mm studs that create an air gap between the substrate and internal finishes, allowing water to drain freely into a perimeter drainage system or sump. The clear construction allows for visual inspection of the substrate during installation, making it ideal for damp-proofing and structural waterproofing.
Key Features & Benefits
- 8mm Stud Height: Provides excellent drainage capacity for high-moisture or below-ground environments.
- Clear HDPE Construction: Enables visibility of substrate for inspection and detailing during installation.
- Moisture Isolation: Prevents moisture and salt transfer from masonry to internal finishes.
- Compatible with Systems: Works with sump pumps, perimeter channels, and sealing accessories for full cavity drain systems.
- Durable & Chemically Resistant: Resistant to alkalis, acids, bacteria, and fungi – ideal for long-term installations.

Courage with a Dose of Strength
Format: Kindle
I believe this book took a lot of courage to write. To me she did a great job of not showing bitterness just love, confusion, and taking back the power. Belle admitted to her struggles and being knocked off her feet by what happened. She asked the questions and was left with No answers. She picked herself up and proved she was strong.
I love that she still believes in her life story. That she still believes in love. But i also admire that she recognized the cycle and is going to break it for her kids.
So, hopefully this book will be another way people realize we need to stop shifting the blame do the victim. Put ownership where it belongs. Stop, listen, and be a friend.

a modern love story
Format: Kindle
This book captured my attention from the first line. She has a way of making you feel the emotions, heartache, and even loving memories she shares. I literally remember stopping to tell my boyfriend I couldn't wait to have kids because of the way she described picking up her children from school and their innocent smiles as soon as they saw her. It's a tragedy and a love story, and a coming to her own all in one. Loved this book!

Memories Are Made of This
Format: Kindle
Belle Burden has overcome a weighty burden—pun intended! Strangers is a book of many colors. There is so much of the overcast gray of heartbreak and estrangement. There is plenty of the blue of heavy disappointment and grief. But happily for every reader, there are so many of the bright colors of happiness and fulfillment. The premise of this memoir has been well documented—a wealthy, privileged life led by a woman of means is interrupted by the abrupt departure of her husband for points unknown. Children remain—-lodged in some difficult ‘tween years. Central is the woman who just happens to be made of pretty stern stuff as it turns out and who is a brilliant writer. Belle Burden is the belle of her own tale. She shares it all with the reader in un-put-down-able prose, sparing nothing, We are richer for reading Belle Burden’s beautifully crafted memoir. The warm glow of hope is there for all to share. Well done!

Surprisingly Unputdownable
Format: Kindle
I read saw several reviews that said this book wasn’t really about anything, and they were right. There was no big drama, no fighting, no headline news. But there was something in the writing that felt profound and I couldn’t stop reading. And I’m glad I didn’t.
In the end for me, this was a story about a marriage, and choices that were made and the strength of a woman who wouldn’t be silent, and the writing that brought so much emotion with it that I wound up feeling all of it so deeply. And when a writer can create those feelings in me, then her book was definitely worth reading.
I highly recommend this book - I don’t think you’ll regret the time you spend in its pages. I know I didn’t.
