If you don't always have access to these sophisticated measuring devices, the question commonly asked is: How do I know if my base is properly compacted? The answer is quite simple. If you follow the guidelines and recommendations which have been presented, your base will be properly compacted and offers you a lifetime of service.
LEN BROWNING, the author, one of the founding members of the Segmental Contractors Institute, also authored "Paving Stone and Retaining Walls: An Overview" in the September/October issue. Next month, he will cover basic tools and their uses.
Welcome Segmental Contractors Institute Members-Proper construction is critical to segmental retaining wall promotion-especially now, as the market emerges and the benefits of mortarless construction are not widely understood. A significant component of our marketing program is dedicated to installation training. It's good to know that SCI has similar interests. Our industry will surely benefit from your efforts.

We think that the new Segmental Contractor division of the MCAA (SCI) is terrific! This new breed of masonry contractor is emerging quite strongly, and one of their prime concerns is establishing the kind of professional standards that the rest of the masonry world has been able to achieve. So, we tip our hat to SCI and wish you all the best for a long and fruitful existence.-Pine Hall Brick, Winston-Salem. NC
